Application filed Apri1 5f1922. I 'SeriaiNo. 549,741.

T 0 all nib-0m it may concern:

Be it known that I, JOHN I. Knees, a citizen of the United States, and a resident of Cleveland, :county of" Cuyahoga, and State of Ohio, have invented a new and use-- ful Improvement in Locks for Grates and -Boxes, of which the following is a specili cation, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The present invention, relating, as indicated, to locks for crates is more particularly directed to an improved type of lock for a shipping crate orbox. One of the principal objects of the invention is the provision of such a lock which may be quickly operated and in which the locking parts shall be protected from injury caused by the rough usage to which such crates are frequently subjected. To the accomplishment of the foregoing and related ends, said invention,

then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing Fig. 1 is a view in perspective of" my improved lock; Fig. 2 is a section on the line 2--2 in Fig. 1; Fig. 3 is a section on the line 3-3 in Fig. 1; and Fig. 1 is a plan view of the staple plate.

In Fig. 1, I have shown a staple plate 1 and a locking hasp 2 which is formed in the usual manner, and consists of a fixed part 3, which may be attached to the cover of the crate or box and a pivot hasp 4. This hasp t is provided with a narrow longitudinally extending slot 5, and in order to lock it, it may be swung over the central portion of the staple plate 1 and into contact therewith, as indicated. in Fig. 2. i

The staple plate 1 is provided with a locking pin 6. This pin is pivotally mounted centrally of the staple plate, the lower end of the pin being formed into a head 7, which is received in a stamped-up boss 8 in the plate. The pin is curved and its free end 9 is flattened and provided with an aperture or eyelet 10 therethrough. The staple plate is also provided with an extending 111g 11 LocKroncaATEsANn Boxes. 'liirw having an aperture or eyelet 12 therethrough, andthis eyelet is adapted to register with the eyelet 12 in one position of the pin 6, which is a position in which this pin extends over the forward or free end let of the hasp, the pin in this manner locking the hasp in place on the plate. A wire 15 may then be threaded through the registering eyelets in the plate and the pin, and sealed to prevent. tampering with the contents of the crate.

To unlock the hasp the seal is broken and the pin 6 is then swung half way round until it extends towards the fixed portion 3 of the hasp, and in this position the hasp may be swung pivotally away from the plate, the slot 5 allowing it to pass over and disengage from the pin.

In such constructions where the crates are subjected to very severe handling the locks, and particularly the pins or staples, are broken or damaged. In order to protect the present pin I provide two curved guards 20 and 21; These guards extend on either side of the hasp and pin and are of sufficient height to extend to at least the top of the pin 6. The pin is mounted substantially centrally between these guards, and the guards are ilorn'ied integral with the staple plate, being pressed out of the plate itself, and are provided with inclined outer surfaces 22 which stiiiens them and prevents distortion or injury of the guards. These guards protect the hasp and the locking pin.

In construction my improved lock is. extremely simple and easy to operate and it provides an economical lock for crates or boxes which is well adapted to withstand extremely severe use.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, pro vided the means stated by any of the following claims or the equivalent of such stated means be employed.

I therefore particularlypoint out and distinctly claim as my invention 1. A. device of the character described comprising a staple plate provided with two integrally formed spaced guards at the sides and an apertured lug at the center of one end, said plate having a stamped boss in the center provided with an aperture, a beaded pin mounted through such aperture and having. an eyelet at its free end adapted to register in one position with such aperture in said lug, and a hasp provided with a slot positioned to engage over the pin in one position.

2. A. device of the character described comprising a staple plate provided with two. integrally formed spaced guards at the sides and an apertured lug at the center of one end, said plate having a stamped boss in the center provided with an aperture, a beaded pin mounted through such aperture and having an eyelet at its free end adapted to register in one position with such aperture in said lug, said beaded pin being of less height than said guard members, and a hasp provided with a slot positioned to engage over the pin in one position.

3. In a device of the character described,

the combination of a staple plate provided at the sides to two integrally rolled beads curved to form side guards, said plate having an apertured lug extending centrally from one end and a centrally located stamped up, apertured boss, a curved beaded pin pivota-lly mounted through such apertured boss and having an eyelet at its free end adapted to register in one position with such aperture in said lug, said pin being adapted to pivot between said side guards and extend ing above said plate a less distance than said guards, and a hasp provided with a slot positioued to engage over said pin in one position.

Signed by me this 28th day of March, 1922.

JOHN P. KUBES.
